Protip, in general: Buy workwear. No, not high-viz stuff, look at trousers for plumbers, for carpenters, cooks, catering, etc, you'll find good quality at good prices instead of good quality at insane prices (fashion) or shoddy quality at insane (but the other direction) prices (fast fashion). They will have a cut that first and foremost focuses on comfort and function (i.e. you can squat in them), only then go for looking somewhat stylish. Which, yes, works. Colour choice will be limited, but black will be among them so stop complaining.
